Electric force is a fundamental force of nature that describes the attraction or repulsion between two charged objects. It is caused by the interactions between the electric charges of the objects.
Electric force is calculated using Coulomb's law, which states that the force between two charged objects is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.
The unit of electric force is Newton (N), which is the same unit used to measure other types of forces such as gravity or friction.
The direction of electric force depends on the charges of the objects. Like charges (positive-positive or negative-negative) repel each other, while opposite charges (positive-negative or negative-positive) attract each other.
Electric force has many real-life applications, such as in the operation of electronic devices, generation of electricity, and functioning of the human nervous system. It is also used in industrial processes, such as electroplating and electrostatic painting.
